PLEASE HELP! The following graph shows Kelly's heart rate during a workout. During which time period did her heart rate increase? Decrease? Remain constant? Show your work

from 5-15 minutes her heart rate increased as shown on the table

from 15to 35min her heart rate stayed constant

from 35min to 45 minutes her heart rate decreased

the quotient is 4x^2 - 27x + 167 with a remainder of -996

step-by-step explanation:

in synthetic division, use -6 as the divisor and use the coefficients {4, -3, 5, 6}:

-6     )   4     -3     5     6

                -24   162 -1002

          4   -27   167   -996

thus, the quotient is 4x^2 - 27x + 167 with a remainder of -996.

note:   your "4x°-3x+5x+6" is ambiguous / incomplete.   i had to assume that you meant '4x^3 - 3x^2 + 5x + 6."
